Pilot to bombardier
Although the picture isn't too good, I thought this beetle deserved an entry. I believe it is one of the bombardier beetles of the genus Brachinus. We found it under an old cast iron pot that was out in the woods. When we lifted the pot, it scurried to find cover and seemed determined not to have its picture taken. So determined, in fact, that it "shot" at us. When we tried to slow it down, it released an explosive cloud of some pretty foul-smelling chemicals from its back-end. We could hear a muffled pop and actually see the puff of the gas. Pretty impressive stuff. After taking a few pictures we lowered the pot back down and let the beetle get back to whatever it was doing before we so rudely interrupted it.
